SHEET-TRANSFERRING DEVICE FOR PRINTING-PRESSES- SPECIFICATION forming part of Letters Patent No. 774,573, dated November 8, 1904. Application filed March 9, 1904. Serial No. 197,234. No modeln To all whom it may concern:

Be it known that I, GEORGE P. FENNER, a citizen of the United States, residing at New London, in the county of New London and State of Connecticut, have invented new and useful Improvements in Sheet-Transferring Devices for Printing-Presses, of which the following is a specification.

This invention relates to sheet-transferring devices for printing-presses, and by means thereof the delivery of a sheet is facilitated; and the invention resides in certain features of construction set forth in the following specification and claims and illustrated in the annexed drawings, in which Figure l is a sectional side elevation of an impression-cylinder and delivery device embodying this invention. Fig. 2 is a view like Fig. 1, showing a sheet about to be taken 01f the cylinder. Fig. 3 is a plan view of Fig. 1. Fig. 4 is a perspective view of a tympanclamp.

In the drawings is shown an impression-- cylinder 6.

The letter (Z indicates atympan-clamp. A spring a, such as a thin piece or strip of steel, is secured or fastened to the tympan-clamp. At the top or upper part of the clamp is a rib d at one side of or extended laterally from the clamp. The spring-strip resting on the rib is prevented from being bent down or out of shape. The free end portion of the spring projects over onto the impression-surface, as indicated at a. Such free end portion is bent or extended laterally, as shown.

A wire or delivery finger is shown at c. As the spring is carried about by the cylinder the laterally-extended portion of the spring passes onto the delivery-finger. The finger picks up the steel or spring strips, as also the edge portion of the sheet thereon. The sheet can thus be delivered with very small gripperhold or without the sheet projecting over the front of the impression edge of the cylinder. What I claim as my invention, and desire to secure by Letters Patent, is-

1. A cylinder havinga spring piece or strip made to underlie a sheet thereon and a delivery-finger to pick up the spring and sheet, said finger arranged at one side of the plane of revolution of the spring-piece and having a portion projecting into such plane.

2. A cylinder having a spring-piece adapted to project onto the same, and a deliveryfinger arranged outside of the cylinder and adapted to engage the spring to cause a sheet to pass upon the finger.

3. A cylinder, a tympan-clamp, a spring carried by the cylinder and adapted to project thereupon, and a delivery-finger arranged outside the cylinder and adapted to engage the spring causing thereby a sheet to pass upon the finger after the tympan is released.

4. A cylinder having a spring piece or strip having its free end extended or bent laterally, and a delivery-finger over which said free end is made to pass to be lifted together with a sheet or edge lying thereon.

5. A tympan-clamp having a side rib, a spring piece or strip extended onto the rib and a delivery-finger made to engage the spring.

6. An impression cylinder having a tympan-clamp and an elastic lip made to project onto the impression-surface to hold up a sheet, said lip by its elasticity being made to spring or lie onto the cylinder to underlie the sheet.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

GEORGE P. FENNER.
